The capacity of power accumulation systems integrated into PV modules will grow exponentially in the coming five years and at the end of 2017 it will reach five gigawatt-hours, Activ Solar Chief Operating Officer Johann Harter has said, referring to the forecast of IHS international company.

"Despite the fact that Ukraine remains a new solar power market, it's important to start discussing the possibilities of accumulating power now. Inexpensive and large-scale solutions will be the Holy Grail for renewable energy, as they will allow solar and wind power plants to ensure the continuous flow of energy to the power grid," he said at the Renewable Energy & Energy Efficiency Forum in Kyiv on Tuesday.

Harter said that today there are several efficient solutions allowing the accumulation of power generated by solar power plants during the day that can be realized in Ukraine –pumped-hydroelectric storage, storage of compressed air, and the power-to-gas solution.

He also said that in 2013, a program on the stimulation of the use of systems that accumulate power generated by PV modules was launched in Germany with the budget of EUR 25 million. Both households and commercial companies received access to the program.

Ukraine over the few last years has been actively developing renewable energy to improve its energy security and strengthen its energy independence, as well as resolve local problems of energy supply and reduce the negative impact of energy generation on the environment.

According to the National Commission for Energy Regulation, the total installed capacity of Ukraine's operating solar power plants last year doubled to 372 MW.

Ukraine has more than 100 projects of solar power plants with a total capacity of over 1,400 MW at various stages of implementation. Such objects are built by companies from Portugal, Germany, France, Austria, the Czech Republic, and Israel.
